Abstract

Controlled density semiconducting oxide arrays are highly desirable for matching nanometer length scales specific to emerging applications. This work demonstrates a facile one-step method for templating hydrothermal growth which provides arrays with high-fidelity tuning of nanorod spacing and diameter. This solution-based method leverages the selective swelling of block copolymer micelle templates, which can be rationally designed by tuning molecular weight and volume fraction.

Keywords: ZnO nanorod array; block copolymer templating; bulk heterojunction photovoltaics; hydrothermal synthesis; templated synthesis.
